Title: Defrosting method for a microwave oven using an infrared sensor
Inventor: KIM WON-HO
IPC: F24C7/02
Filed: 1999-11-02
Abstract: Defrost method for accurately defrosting food to be defrosted, regardless of frozen degree and presence/absence of receptacle for food to be defrosted. The defrosting method includes the steps of: determining an initial value by detecting a surface temperature of food to defrost; determining a defrost completion value in accordance with the initial value which is determined in the step of determining the initial value; detecting a current value of an infrared sensor at a regular time basis while driving a magnetron; and completing the defrosting process if the current value reaches the completion value. An output value of the infrared sensor is detected at a predetermined regular time basis while a rotatable tray for placing the food is rotated, and the initial value is obtained from the lowest output value among a plurality of output values which are detected. A gap between the initial value and the completion value is divided into at least two divisions, and a power rate of the magnetron is varied in accordance with the respective divisions. The power rate of the magnetron of the respective divisions, is decreased from the value which is closer to the initial value to the value which is closer to the completion value.

Title: Method for data compression
Inventor: HALE IRA D
IPC: H03M7/30
Filed: 1998-05-06
Abstract: The widely used JPEG standard algorithm for two-dimensional image compression may be adapted for compression of arrays of any dimension and data type, specifically for arrays of seismic data. Because the JPEG algorithm processes, more or less independently, small subsets (8 x 8 blocks) of larger images or arrays of data, such adaptations are particularly useful in applications that cannot maintain a large, uncompressed, multi-dimensional array in computer memory. JPEG-like methods enable compression and decompression of large arrays by iteration over sub-arrays that are small enough to reside in memory.  These algorithms lead to the concept of a compressed virtual memory. Special care must be taken in JPEG-like algorithms to avoid blocking artifacts, which are discontinuities between blocks of data that are compressed and decompressed independently. Fortunately, computationally efficient methods for suppressing these artifacts are well known. Of these methods, one has been adopted that enables much of the JPEG method to be reused. The JPEG-like method of the invention uses the JPEG methods for discrete cosine transform (although the forward and inverse transforms are reversed), and for Huffman encoding of the quantized transform coefficients. The method differs from JPEGs primarily in additional steps taken to avoid blocking artifacts, and in the quantization of transform coefficients.
Patent CA-2291576-A1 (CA)
Inventor: LEVENGOOD WILLIAM C
IPC: A61B5/04
Filed: 1999-12-03
Abstract: A method and apparatus is provided for detecting and recording a specific type of electric pulse induced in metal electrodes by the living tissue of humans, other animals or plants, and by certain organic and inorganic models of such living tissue. The purely passive system detects the electric energy produced by the living source as it interacts with the crystalline lattice of conductive metal electrodes to produce a train of oscillating pulses, the amplitude of whose envelope decays as a linear function of log-time. Specific aspects of these pulses can be used to study the state of the living, or non-living, source and to detect changes in this state over time. The results of such studies of living sources can be interpreted, respectively, in terms of the state of health, or disease, of the source and of changes in the state of health, or disease, of the source, and can thus be used to recognize, characterize and evaluate conditions of the living organism and to quantify the effects of therapies and putative therapies.

Title: Neurotrophic factor receptors
Inventor: WEN DUANZHI
IPC: A61K38/00
Filed: 1998-04-27
Abstract: The present invention relates to glial cell line-derived neurotrophic factor (GDNF), a potent neurotrophin that exhibits a broad spectrum of biological activities on a variety of cell types from both the central and peripheral nervous systems. The present invention involves the cloning and characterization of receptors for GDNF. Nucleic acid and amino acid sequences are described for GDNFR protein products. A hydrophobic domain with the features of a signal peptide is found at the amino terminus, while a second hydrophobic domain at the carboxy terminus is involved in the linkage of the receptor to the cell membrane. The lack of a transmembrane domain and cytoplasmic region indicates that GDNFR requires one or more accessory molecules in order to mediate transmenbrane signaling. GDNFR mRNA is widely distributed in both nervous system and non-neural tissues, consistent with the similar distribution found for GDNF.

Title: Short body endoprosthesis
Inventor: WEISER MICHAEL F
IPC: A61F2/06
Filed: 1998-09-04
Abstract: The invention comprises, inter-alia, endoprosthetic implants for treating vascular defects, including abdominal aortic aneurysms.  Implants according to the invention have a short main body that can be positioned within a patient's aorta at a position above the renal end of an aortic aneurysm. The short main body includes a proximal, or renal, face that redirects the flow of blood into the openings of channels that can carry blood past the aneurysm. In this way, the flow of blood through the aorta is diverted into the two passageways and through the main body of the implant. Fluid exiting the implant can be carried by leg extensions and delivered to a healthy part of the patient's aorta or the iliac arteries. Accordingly, the implant provides a system for allowing blood traveling through the aorta to be carried by a vascular graft that spans an aortic aneurysm, thereby relieving fluid pressure on the thin wall of aortic aneurysm, and reducing the risk of death caused by a ruptured aneurysm.
